SPECIFICATION forming part of Letters Patent No. 346,859, dated August3, 1886.

Application filed October 23, 1885. Serial No. 180,767. (No model.)

To all whom it may concern:

Be it known that I, JASPER N. NUTT, of Sidney, in the county of Shelbyand State of Ohio, have invented a new and useful improvement in Ghurns,of which the following is a description.

My invention is an improvement in churns, and especially in that classof such machines known as rotary dashers; and it consists in certainnovel constructions, combinations, and arrangements of parts, as will bedescribed and claimed.

In the drawings, Figure 1 is a top plan view of my churn with the coverremoved. Fig. 2 is a side view thereof with the cover in place. Fig. 3is a longitudinal section of the churn box and cover, the dashers beingremoved; and Figs. 4 and 5 are detail views, on a reduced scale, of theinner side of, respect' ively, the end and side pieces of the churnbox,as will be described.

Each end piece A of the churn-body is formed at its upper edges with arabbet, at, extending almost to its opposite sides. From U the ends ofthe rabbet grooves aextend downward, and communicate near their lowerends with a horizontal groove, o The grooves a are fitted to receive theside pieces, B, and the grooves a the ends of the bottom 0. The sides Bare grooved at b, near their lower ends, to receive the side edges ofthe bottom. The sides terminate in plane with the base of rabbet a, andtheir upper edges form the base of the side wing of the rabbet, whichextends around the mouth of the box. The upright walls of such sidewings are formed of battenbars D, secured alongside of and projectedslightly above the sides 13, and abutting at their ends flush againstthe end pieces A, as most clearly shown in Fig. 1. Metallic cornerclamps may be secured on the upper corners, to give rigidity andstrength to the box. The top D is formed with a rabbet, (l, which fitsthe rabbet of the box, as shown in Fig. 3. Legs E are secured to thesides of the box against the projecting portions of ends A, and theirupper ends are preferably lapped under the lower edges of the cornerclamps, to prevent any warping or other spreading of the parts. side ofthe box, and is provided with a stud, f, for the drive-wheel, and withbearings for the ends of the dasher-shafts. These shafts G Gr arejournaled in the sides of the box, and have pinions g g on one end, asshown.

The master or drive gear H has a suitable crank, and is journaledbetween the pinions g g. I form this gear H with external teeth, h,meshed with pinion g, and with internal teeth, 11/, meshed with piniong, and it oper- 6o ates to revolve the dashers in opposite directions.

As will be seen on reference to Fig. 2, the number of external teeth, h,on the masterwheel isjust equal to the'number of internal 6 teeth, h, onsaid wheel, and also that the pinions 5 and g are of the same size. Bythis construction of the gearing the dasher-shafts are driven in unison,whereby the dashers are made to perform an equal amount of work.

Through each shaft G, at right angles to the axis thereof, are passedthree rods, forming arms J on each side of the shaft, on which aresecured perforated dasher-blades I. These rods are passed through theshaft in such a manner that the arms on each side will stand at an angleof about sixty degrees to each other, and the blades I are attached tothe arms in such a manner as to stand obliquely to the axis of theshaft, the blade on one arm being inclined in a reverse direction tothat on the opposite arm on the other side of the shaft. Thedasher-shafts are located a considerable distance apart, as seen in Fig.1, so as to leave a space in the middle portion of the box not traversedby the dashers.

By the above-described arrangement of the dasher mechanism the creamwill the thrown alternately to the sides and the center of the box,causing the butter to settle in the mido dle portion of the churn, whereit is left undisturbed by the dashers until the churning is completed.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

The combination, with a churn-box, of two shafts, each of which isprovided with dasher- A bearing-plate, F, is secured to one 50 bladesset obliquely to its axis, the arms traversed by the blades, andmechanism, subbearing the blades radiating from the shaft at stantiallyas described, for driving the shafts 10 an angle to each other ofI[about sixty dein opposite directions at the same speed. rees the bladeon one arm eing inclined in r 5 g reverse direction to that on theopposite JASPER NUDT' arm on the other side of the shaft, the shaftsVvitnesses: being placed a suflicient distance apart to HERMON O. AYREs,leave a space in the middle of the box not ALBERT WILSON.
